Dallas — the school district but also the city — has been shaped over the past century by hundreds of thousands of individual decisions like this one, made by families seeking the best education for their kids. It has not gone well for Dallas. Those with the means have almost uniformly opted out of DISD, moving to the suburbs or sending kids to private or charter schools. White families fled the district en masse in the decades following desegregation. Middle-class black and Hispanic families weren’t far behind (The Dallas Observer).
